The G250 has something of a cult status as does the Mark 10. You might find a new Deep Six/DGX might be competitive in price.
A G250 from Simon is also a good route to the best second stage ever
.
Contrary to common opinion that one needs a Mercedes to get groceries when a Camery is more reliable and equally capable of getting to the grocery store. The scuba corollary would be a set of G250s from Simon and a brand new Scubapro Mark 2 Evo unbalanced first stage. Dirt simple, possibly the most reliable first stage ever made and completely adequate when coupled with a balanced second stage like a G250 for sport diving. My last 110 dives have been on exactly that and with several dives below 100 feet and one to nearly 150 feet. The only reason a Mark 2 even has a service interval is to satisfy the legal department. I bought one in Bonaire at the SP dealer there for $200 but alas, everything cost more in the USA dealer network. Like pharmaceuticals, we in North America pay more for the same.
